• Naomi B. Robbins: How to Avoid Some Common Graphical Mistakes

    The idea for this session came from a question asked at our last meetup. An audience member asked what is wrong with pie charts. I decided we need a program that is more basic than our usual ones. Although this talk will be elementary, I suspect that most attendees will identify with some of the mistakes shown. Abstract: Good graphs are extremely powerful tools for communicating quantitative information clearly and accurately. Unfortunately, many of the graphs we see today are poor graphs that confuse, mislead or deceive the reader. These poor graphs often occur because the graph designer is not familiar with the principles of effective graphs or because the software used has a poor choice of default settings. We point out some of these graphical mistakes. In most cases, very simple changes make the resulting graphs easier for the reader to understand. In addition, we show some common mistakes with tables. We end with some useful little-known graph forms that communicate the data more clearly than the everyday graphs that are more commonly used. Bio: Naomi is a consultant and seminar leader who specializes in the graphical display of data. She offers keynotes, lunch and learns, short courses and workshops to train employees of corporations and organizations on the effective presentation of data. She also reviews documents and presentations for clients, suggesting improvements or alternative presentations as appropriate. She is the author of "Creating More Effective Graphs." Naomi is a Past-chair of the Statistical Graphics Section of the American Statistical Association and is the organizer of the Data Visualization New York Meetup.

  • Visualization Landscape and Grammar of Graphics

    StartLab - Bank of Ireland


    Speaker 1: Lee Medoff Title: Surveying the Data Visualization Landscape Abstract: What makes the visual representation of data meaningful and appealing? What are some of the current trends in data visualization, including those that have been enabled by technology? And who are the ‘tastemakers’ in the industry? We consider these questions, surveying recent representations of data – examining, recreating and modifying some of the best and worst recent data visualizations. Bio: Lee Medoff is the founder and CEO of Hedgehog Analytics, a data and analytics consulting firm that provides analytics services and solutions. The firm advises tech startups as well. Lee began his career in analytics with Y&R, a New York ad agency, then moved into finance, beginning with the Decision Sciences group of the credit card division of JPMorgan Chase, where he developed models to optimize the return on the bank’s card portfolio. He also worked at the Federal Reserve Bank of New York and Moody’s Analytics, where he oversaw analytics teams in New York and India developing and customizing models for the firm’s software. He holds advanced degrees in Statistics from Columbia University and Economics from New York University. Speaker 2: Ganes Kesari Title: Grammar of Graphics: The Secret Sauce of Powerful Data Stories Abstract: Data Visualization can be a powerful medium to tell stories from data. However, while creating visual representations, people often make the mistake of dipping into a catalog of ready-made charts and preset visual templates. This blunder is the equivalent of writing English prose using a rigid list of sentences, as opposed to the conventional way of stringing together words elegantly, by blending in the grammatical elements. This session will introduce the concept of ‘Grammar of Graphics’ from Leland Wilkinson, and demonstrate the fluid construction of elegant visuals, layer by layer and with practical examples. As a bonus, you’ll learn how to invent your own charts. Bio: Ganes co-founded Gramener, where he heads Analytics and Innovation in Data science. He advises enterprises on deriving value from data science initiatives. He is passionate about the confluence of machine learning, information design and data-driven business leadership. More about his data pursuits can be found at https://gkesari.com. Thanks to Glantus US for organizing most of this event including finding a venue for us. I encourage other members to contribute by organizing a single event. Kristen Sosulski, author of Data Visualization Made Simple, will speak at a meetup on November 26 if I can find a venue. --------------------- Announcements: The organizers of the DataEngConf NYC (See more here: http://bit.ly/NYC-Event), the annual no bullshit data event for deeply technical professionals have offered our members a $160 discount coupon code: “NYCData18” that can be redeemed by following this link: bit.ly/NYC-Tickets18.

  • Financial Data Visualization

    Metis New York

    There will be two speakers on visualizing financial data. Joanna Kao Abstract: This talk will cover translating complicated graphics from financial reports into stories that can be consumed by anyone, designing for different mediums so content can be delivered straight to where our readers already are and factors to consider when creating accessible graphics. Bio: Joanna S. Kao is a visual journalist at the Financial Times and teaches courses on accessibility and data visualization at the New School. She creates immersive long form story templates, experiments with audio storytelling and explores theater-related data in her spare time. She has a bachelors degree in computer science from the Massachusetts Institute of Technology and enjoys living at the intersection of computer science, design and journalism. Julie Rodriquez Abstract: Data visualizations are often compromised representations that may limit our ability to understand the full story or lead us to shortsighted conclusions. Between multiple screen displays, tables of data, and basic charts that only show a limited perspective of the data, we are left with subpar tools to combine and analyze data. Collectively, we know we need to improve our data experiences, as well as our ability to see the main issues, discover the hidden details, make connections, and compare the top ideas. And increasing amounts of data only heighten the need to do more with the data we have and ensure our decisions are well considered. As a result, we also need better methods to navigate data and extract multiple questions from datasets so that our follow up queries are only a click away. Bio: Julie Rodriguez is vice president of product management and user experience at Eagle Investment Systems. An experience designer focusing on user research, analysis, and design for complex systems, Julie has patented her work in data visualizations for MATLAB and publishes industry articles on user experience and data analysis and visualization. She is the coauthor of Visualizing Financial Data, a book about visualization techniques and design principles that includes over 250 visuals depicting quantitative data.
